I've found both QSR Nvivo and Dedoose (an online programme) useful.

For qualitative analysis, which software is more effective?

You can refer to the following links:

I think that depends on the methodological approach, but most common are Atlas Ti, MAXQDA  and QDA Miner Lite are more popular.

Atlas ti.7 is easy and better, according to me.

Hi Abu,

You can also refer to this link as well.  Wising you all the best.

if that for I will Always go for IBM Watson.

But As for Cost Effective MAXQDA is qualitative analysis software both for windows and MAC platform.Its user friendly and Mixed method Research.

Again An open Source Free research application, I can mention that The Qualitative Data Analysis Program (QDAP): Accurate and reliable coding (or labeling) using humans and machines is central to both the qualitative research and the #bigdata text analytics process. For new and experienced researchers, learning advanced project management skills adds hours of struggle. Since 2005, Qualitative Data Analysis Program (QDAP) coders and project managers have delivered large-scale, high value-added, reliable and accurate annotated text data in a timely and expert manner. The QDAP approach to qualitative research grows out of more than a decade of working on projects funded by the National Science Foundation, the National Institutes of Health, DARPA, the Smithsonian and others. Our combination of software, methods, experience, and novel forms of text analytics measurement present a uniquely scientific research support offering with applications across the disciplines.
